The RamSan-620 is a rack-mounted SLC NAND
Flash SSD that provides plenty of shareable, high performance storage
for IT organizations that need to respond to the growing storage and
performance needs of their users and applications. It is a greener,
more efficient alternative to hard disk drive-based systems. The
RamSan-620 has extremely low latency and delivers 250,000 IOPS of
sustained performance, compared to the 300 IOPS that a high end
mechanical disk drive can achieve. SLC Flash and innovative controller
designs give the RamSan-620 enterprise reliability and data
protection. With capacity options of 2 � 5TB in a 2U enclosure that
uses only 325 Watts, the RamSan-620 can handle data growth very
efficiently. It installs quickly and easily and is managed in the same
way as our other RamSan systems, integrating seamlessly into almost
any SAN environment using Fibre Channel or InfiniBand connectivity.
The RamSan-620 is extremely versatile and especially well suited for
performance-demanding applications such as data warehouses, online
transaction processing, batch processing, and video editing.

Flash has enabled TMS to deliver high
performance storage solutions to a much broader customer base. For
over 30 years we have been at the forefront of storage performance and
application acceleration for enterprises. With this 15th generation
RamSan-620 we are combining expertise and technology to solve
challenging problems of performance and efficiency in enterprises of
all types and sizes. The RamSan-620 is a breakthrough of giant green
storage that is affordable for mainstream IT shops across industries.

The RamSan-620
offers scalable performance and affordable high capacity that is space
and power efficient as well. A single unit provides from 2 to 5TB of
reliable Single Level Cell (SLC) Flash, making the RamSan-620 the
highest capacity SLC Flash SSD on the market. It also leads the
industry in performance with 250,000 sustained I/Os per second (IOPS)
for random reads and random writes. Throughput is 3GB per
second and latency ranges from 80 to 200 microseconds, 25 times less
than high performance hard disk drives.

The RamSan-620
is a green IT choice, occupying only 2U of rack space and requiring
only 325 Watts of power. In order to achieve similar performance, hard
disk solutions would require as many as 500 drives, occupy 36 disk
enclosures requiring nearly three full racks, consume over 7,000
Watts, and cost upwards of half a million dollars by the time the
enclosures and controllers were included.

Each RamSan-620 unit can support 2 to 8
Fibre Channel (FC-140) or InfiniBand (IB-140) links. Installation and
management are simple, with embedded management capabilities and clear
displays. One or more RamSan-620s can easily be integrated into a
mixed storage infrastructure and monitored and managed through a
common management framework.

Automatic Error Checking
Storage data integrity is provided by the use of SLC Flash chips with
two independent methods of ECC. Each Flash chip incorporates an ECC
data field within the chip for initial checking. Additionally, each
set of Flash chips is organized as a board-level RAID; thereby
eliminating any single chip failure from corrupting data.
